WATER-HEATER.

Specification of Letters Patent.

Patented July 10, 1917.

Application filed September 23, 1913. Serial No. 791,348.

a citizen of the United States, residing at Scammon, in the county of Cherokee and State of Kansas, have invented certain new and useful Improvements in-Water-Heaters, and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in water heaters and has for its object the provision of a device which is adapted to heat water at a minimum of expense.

A further object of my invention is the provision of such a device which will permit the user to disconnect the same and provide openings of sufficient size to permit the device to be readily cleaned.

A further object of my invention is the provision of such a device which may be used either with a gas burner 'or it may be used in connection with a stove of the ordinary construction.

With the above and other objects in view I will now proceed to describe my -inven tion in the following specification and accompanying drawings, in which,

Figure 1 is a longitudinal sectional view of my improved heater showing the same in position for operation in comiection with a gas burner,

Fig. 2 is a view of my improved water heater showing the same as it would appear when applied to a stove of the ordinary construction, Fig. 3 is a detail transverse sectional view of the water contalning chamber taken on line 3-3 of Fig. 1, and

Fig. 4: is a detail plan view of one of v the blocks which is adapted to be inserted in the ends of the heater.

Referring to the drawings by characters of reference 1 indicates an ordinary boiler which is connected to the water system in the usual manner. This boiler is provided with the cold water inlet pipe 2 and the hot water outlet pipe 3, respectively. Circulation through the boiler is Obtained through the medium of the pipe 4, the T-connection 5, the pipe 6, the elbow 7 and the nipple 8. The upper end of this nipple is screw threaded as clearly illustrated in screw threaded aperture formed in the plug illustrated in Fig. 4. After passing through the heater the water continues to circulate upwardly through the pipe 9, the elbow 10, the pipe 11 and back through the T-connection 12 to the boiler 1.

My improved heater which is interposed between the upper end of the nipple 8 and the lower end of the pipe 9 preferably comprises the cylindrical casing 13 having formed integrally therewith the top 14 and secured at the lower end thereof the bottom 15 which in turn is provided with the aperture 16 through which air may be taken to feed the flame of an ordinary gas burner, illustrated generally by the numeral 17 and fed from the pipe 18. A suitable cylindrical casing 19 having formed integrally therewith the outstanding lugs 20 is provided and is of less diameter than the casing 13 in order to provide a heat chamber intermediate the casing 19 and the casing 13. The ends of the casing 19 are preferably provided with the internally screw threaded apertures 21 with which the plugs, indicated generally by the numeral 22, are adapted to cooperate and form closures for said ends.

These plugs 22, preferably comprise the externally cylindrical screw threaded body portion 23 having formed at the outer end thereof the flange 24 which is preferably hexagonal, as illustrated in Fig. 4. An internally screw threaded aperture 25 is centrally located with relation to the plugs and is adapted to receive the screw threaded ends of the nipple 8 and the pipe 9, as will be clearly seen upon referring to Fig. 1.

In Fig. 2 of the drawings I have shown my improved water heater as it would appear when applied to a stove of the ordinary construction and it will be apparent that the only changesin said stove are the provision of the apertures 26 and 27, through which the pipes 6 and 9 respectively are adapted to extend.

It will be clearly seen from the foregoing that in use the water heater is connected in the usual manner to a boiler of the ordinary type and upon becoming heated the water willclrculate therethrough in the usual way.

Owing to the peculiar construction of the lugs 20 which are substantially triangular in cross section it will be apparent that considerable more surface will be presented to the heat and therefore less fuel will be re- Fig. 1 and is adapted to enter an internally quired to produce the same amount of hot water than was necessary in the old type of water heater. A further advantage will be gained from the use of the enlarged removable plugs as the operator will be enabled to reach the interior of the heater in a much more satisfactory way than with the old type of heater. using a coil of pipe or the like. as will be a simple matter to insert the hand through the opening formed in the end of the heater when it is desired that the heater be cleaned.

'hile in the foregoing I have shown and described the preferred embodiment of my invention I wish itto be understood that I may change the specific arrangement and combination of parts without in anyway departing from the spirit and scope of my invention as defined in the appended claim.

IVhat is claimed is A water heater including a cylindrical body, closures at the ends of the body,

pyramidical lugs formed integrally with and extending outwardly from the outer side of the body with their bases disposed outermost. said lugs being arranged in circular and longitudinal series, with each series and the lugs of each series relatively spaced but a short distance to provide a maximum heating surface, a cylindrical casing inclosing the body and having its side wall arranged in close proximity to the bases of the lugs to cause the heat to circulate through all of the spaces between the lugs and between the bases. and arranged so as to carry the heat to engage the outside of the body. and all of the sides or faces of the lugs.

In testimony whereof I aflix my signature in presence of two witnesses.

. CHARLES R. KEITER.
